Joff Filion called the meeting to order on, August 4, 2004 at the Holiday Inn in Palatka at 12:00 PM.

Present at the meeting were: John Griffin, Charles Crain, Dallas Stratton, Cliff Wilson, Jim Lindahl, Bill Thompson, Joff Filion, Taylor Sams, Andrew Schirmacher, Richard Davis, Mike Timpanaro, Phil Dunnington, Don Brindley, Ron Rowe, Mark Nechvatal, Jimmy Douglas, James Zimmerman, Randy Leonard, Will Franke, Wayne Zeigler, and Alan Waters.

The minutes were approved as sent out; John Griffin gave the invocation and led The Pledge of Allegiance.
Treasury Report: Dallas Stratton said all bills are paid and we are solvent.

Old Business: At last Months meeting a gentleman (Eric Brunn) from UF (University of Florida) presented a question thru the chairman. Due to the complexity of the question I have attached a copy of his perplexity. There was some conversation amongst all at the meeting. The end resolve was that what the contractor had installed should be accepted.

Joff Filion presented Don Brindley with a clock/plaque for his services as Education Chairman for 2003/2004

New Business: Dave Chamberlain of Fox, Rowden, McBrayer will give a presentation of the Cadweld Plus system at the September meeting. This presentation will take approximately one and a quarter hour. Every attendee will receive a certification card on the use of the system. Due to time restraints we will need to start the meeting at 11:45.So please plan to attend and arrive early.

Don Brindley wanted to remind all of the upcoming 2004 Southern Section meeting. It will be in Wilmington, North Carolina on October 10-13 2004.

Don Brindley announced that U.L. laboratories has revised their Authority Having Jurisdiction website. You can visit this site at www.ul.com/regulators or you can contact Scott Wilson (Account manager with UL) at 1-877-854-3577 Monday-Friday 7:00 A.M –6:00 P.M.

Andrew Schirmacher sparked a conversation by distributing some specification sheets on the Photoelectric Smoke Alarm.
These Alarms are engineered to help prevent nuisance alarms, apparently steam and kitchen smoke is less likely to activate it. This may be helpful when areas near baths and kitchens need smoke protection. Jimmy Douglas brought up the location of smoke alarms outside of bedrooms; the question being is there footage from the doorway that needs to be observed? The consensus was that the manufactures recommendations should be followed. This seems to be 15’ so that a 30’ hallway would only require one. However it was also agreed that if the blueprints are drawn with two then that would be a determining factor.

Philip Dunnington brought up kitchen outlets other than Residential. Article 210.8B. The code is very specific in this area, each and every 15 & 20 amp, 120-volt receptacle shall be GFCI protected. The only exception does us little good in Florida. This may present a problem with cord connected refrigeration equipment that will not operate properly under GFCI protection. These items will need to be hard wired if they are to avoid the GFCI of coarse they need to be listed for direct wiring.

Philip also brought up wall-mounted luminaries over a tub or Jacuzzi style tub. (Article 410) As long as the luminary is listed and suitable for damp location the code will allow it in the “Zone” of the tub.


Joff Filion pulled Mike Timpanaro’s name from the hat for the 50/50 draw. Lucky Mike.

The next meeting will be held at the Holiday Inn in Palatka at 11:45, September 1, 2004.


Respectfully Submitted,


Alan L. Waters
Secretary





Q: What is the minimum sized equipment grounding conductor required by the NEC to be installed in the paralleled raceways?
Situation:
An installation consists of a 225-amp feeder from a circuit breaker with a 4/0 conductor, goes into a j-box where he changes over to two sets of parallel 4/0 conductors per phase, one set in each of two 2" metal raceways.
The feeder length continues approximately 300 feet where another changeover back to a single set of 4/0 conductors occurs in a second j-box and that set terminates in a disconnect. The ungrounded conductor is increased in size for voltage drop.
Where there is a single set of 4/0 conductors the installed equipment-grounding conductor is a #4 AWG.
Installed in each of the paralleled raceways is a single #4 AWG.
2002 NEC - 250.122(B) (requires adjustment of the EGC size to be proportional to any adjustment in the ungrounded conductor size)
2002 NEC - 250.122[F] Conductors in Parallel. Where conductors are run in parallel in multiple raceways or cables as permitted in 310.4/ the equipment grounding conductors, where used/ shall be run in parallel in each raceway or cable. One of the methods in 250.122(F)(1) or (2) shall be used to ensure the equipment grounding conductors are protected. (1) Each parallel equipment-grounding conductor shall be sized on the basis of the ampere rating of the overcurrent device protecting the circuit conductors in the raceway or cable in accordance with Table 250.122.
I believe the EGC in each of the paralleled raceways needs to be' increased to #1 to be proportional, as required by 250.122(B), AND THEN APPLY 250.122[F], requiring that size conductor to be installed in each raceway. Am I misinterpreting the requirement?
Calculation:
The 4/0 ungrounded conductors are doubled in size. A #4 AWG conductor has an area of 41740 circular mils. Doubling the area of the #4 AWG (2 x 41740) equals 83480 circular mils. The next larger size conductor is 83690 circular mils - #1 AWG.
